Hybrid space solar power stations with laser light emission, using inexhaustible energy of the Sun, provide environmentally clean energy, "green", as well as the development of space solar energy, which is a promising and relevant direction of energy system development in space (providing electric power to space equipment) and in the Earth energy system. Introduction of wireless energy transfer in the form of laser light makes it possible to focus the laser beam safely and with the least losses by semiconductor laser in the range of 0.55-0.75 µm or 1.0-1.1 µm windows of atmospheric transparency (Stage 1) followed by development of efficient fiber lasers with solar pumping at the same wavelength (Stage 2). The three variants of the solar energy transmission process from the Sun to the user in hybrid space solar power plants make it possible to provide electricity to underdeveloped and inaccessible regions without cable power transmission networks (areas in the Russian Far North, Central Siberia, Canada, Greenland, the Arctic and Antarctica, mountainous areas, deserts, natural disasters, disasters and continental shelf areas), as well as mobile, mobile transport and "smart grid" systems.

The problems of irrational expenditure of energy resources leading to the depletion of natural reserves of fossil fuels and environmental pollution are considered. The analysis of the main issues considered in the course of improving solar heat supply systems is carried out. Current scientific, practical and statistical data are systematized, in the process of which ways to increase the efficiency of active solar systems are proposed.
